The Russell-Heckle Seed Company, for the third consecutive 
year, is happy to present the newest strain of cotton bred. by 
the Delta & Pine Land Company—Deltapine 12, a worthy suc- 
cessor to the famous’ Deitapine (D.P.L. 11-A) to which it is 
Similar but superior in most characteristics. 
The Delta & Pine Land Company has been in existence for 
28 years at Scott, Miss. Their business is primarily producing 
eotton for profit. Realizing that called for both the finest type 
of cotton and the highest type of agricultural management, Dr. 
J. W. Fox was put in charge of all agricultural operations and 
Prof. #. C. Ewing in charge of cotton breeding. These two men 
are internationally known as ‘‘tops’’ in their profession. 
There is no ballyhoo about the Delta & Pine Land Com- 
pany; and no mystery about their methods. They welcome visi- 
tors from all over the world, and gladly show them the entire 
plantation, and explain their methods. They are easily the best 
known planters in the South, and have a world-wide reputation 
as cotton breeders. 
The Delta & Pine Land Company; maintains around 200 
acres in experimental work. When a certain variety shows 
distinct advantages over other known varieties, the Company 
adopts the new variety and tests it out by planting a consid- 
erable acreage. When under field conditions, the new variéty 
has demonstrated its merits, they discard all the other varie- 
ties and plant their entire property to the improved variety. 
The Company sells no seed until they are so convinced of its 
merits that they plant their entire acreage in the newly de- 
veloped variety. And that’s the story of D. & P. L. (Delta- 
pine) 12—it has proven the most profitable cotton among all 
those tested for years. When and if they find. a cotton that 
will produce greater revenue, they will adopt it, for after all 
their business is primarily the production of cotton. Their ex- 
perimental work goes on continually. 
DELTAPINE 12 gives a staple ranging from 11-32 inches 
to 14%, inches in the Delta with 1 3-32 inches predominating in 
our 1939 crop. It is of uniform staple and good character and 
classes out high in grade. We did not decide to plant this cotton 
generally until we were assured on the basis of spinning tests 
conducted by the Government that DELTAPINE 12 was equal 
in spinning value to DELTAPINE A (D. & P. L. 11-A). 
Planting Cotton Seed 
DELTAPINE 12 (D. & P. L. 12) has been chosen as a 
worthy successor to the famous DELTAPINE A (Dor. ae 
11-A) to which it is similar but superior in most characteristics. 
DELTAPINE 12 is more productive, has as good staple with 
a better lint turnout and is more disease resistant. In our 
own experimental fields it has produced a four-year average 
yield of 8 per cent more lint per acre than DELTAPINE A 
(D. & P. L. 11-A). DELTAPINE 12 usually gins out more than 
40 per cent lint in the Mississippi Delta and more on uplands. 
In our 1939 crop of 1,868 bales the average lint turnout was 
40.6 per cent. In two variety tests conducted by the Alabama 
Ixxperiment Station in North Alabama the average lint per- 
centage was 44 per cent. Both of these percentages are ex- 
clusive of bagging and ties. 
-DELTAPINE 12 has made a good record in experiment sta- 
tion variety tests. In eight tests at various places in the Miss- 
issippi Delta conducted by the Delta Experiment Station 
DELTAPINE 12 produced the highest average yield per acre, 
leading all other varieties in five of these tests, ranking second 
in two, and third in the one other. As an indication of what 
DELTAPINE 12 will do outside the Delta, the results of variety 
tests of the Alabama stations for 1939 may be cited. Tests 
were conducted at points in North, Central and South Alabama. 
At the two stations in North Alabama DELTAPINE > 12 was_ 
slightly exceeded in average yield by two varieties having 
shorter staple in a list of 30 varieties. At four stations in Cen- 
tral Alabama DELTAPINE 12, with an average staple of 11-32 
inches was slightly outyielded by only one variety with i 
inch staple among 32 varieties. At two locations in the Black 
Belt DELTAPINE 12 produced the highest yield and in the 
South Alabama test, at Monroeville, DELTAPINE 12 also led 
the list. 
In seven other tests, mostly in South Alabama, on wilt 
infested land, DELTAPINE 12 produced the highest average 
yield by 7 per cent in a list of 30 varieties having wilt | re- 
sistance or tolerance. 
In Louisiana, also in a wilt variety test, DELTAPINE 12 
produced the highest yield at the experiment station at Baton 
Rouge. DELTAPINE 12 is not recommended for the worst wilt 
land, but on moderately infested land DELTAPINE 12 undoubt- 
edly will give good results. 
In the Westerns part of the Belt, DELTAPINE 12 haa’ 
proven its value insvariety tests conducted by the Oklahoma 
Experiment Station. In a list of 32 varieties which appeared 
in each of five tests located in Eastern and Central’ Oklahoma, 
DELTAPINE 12 ranked first in yield and in money value per 
acre, 
» 
DELTAPINE 12 possesses an unusual combination of good 
characters, including high yield, good length of staple, high lint 
percentage, easy picking qualities, disease resistance, desirable 
plant type, and wide adaptability. This is a combination of y 
profitable and satisfactory qualities which is unequalled by that 
of any other variety.

*The low yield of Deltapine 11-A for 1938 was due in part to poor stand resulting from defective seed. aor
